I understand that Bung Bo is generally assumed to be the original north mantis set created by Wong Long. I've read elsewhere that 14 roads is Law Gwon Yuk's creation, and I believe I read on Sifu Cotrell's quarterly site that another form is understood to be that of grandmaster Law's Sifu(?) but I can find little else on the remaining sets, their creators and the contibution that each set makes to enhancing the system. I'd really appreciate feedback if this informatiomn is available. I am new to mantis ( 7star in the line of Chiu Leun).

Thanks in advance,
